Question about AT & MT
May be a dumb question to the experts here. As we know on manual, unless you push in the cluch pedal or shift to N, the tranny is always engage the engine. So when is auto tranny disengaged from engine? N or just leave it on D while release the gas pedal.

you should feel the "engine braking" on your automatic.

Yes, automatic transmissions can do "engine braking" just like a manual. However, I would generally recommend against it, especially if you aren't intimately familiar with the car and the transmission. Brakes take an hour and $60 to change. Transmissions cost thousands of dollars to have changed out.
Anyway, you can downshift your auto trans just like a manual. If you click your O/D off button, you'll lock out 4th gear from engaging, which holds the car to using only the first three gears. Generally speaking, if you're under low load or coasting at speeds greater than 40mph and you click O/D off, you'll feel some engine braking as it downshifts into 3rd.

Haha, Maximas probly have the 1st gear lockout- probly second too to prevent that exactly from happening. I had a pontiac before that a friend tried to shift in 2nd but ripped it into first at like 65 i was like ohh **** but it stayed in 2nd. Nissan's probly smarter than to let you shift whatever you want, also has anybody ever had that fail-safe thing come on? You know in the manual where it says if the trans is used in excessive wheel spinning and subsequent hard braking, the O/D light flashes and its in fail-safe? Sorry about all the q's, i have a stick

and I shift enough without shifting back threw almost every gear every time I come to a stop.
I see almost no reason to ever doo this.

What I do is i clutch-out and shift to neutral. Then I just brake. $Transmission > $Brakes.

...Some aspects of the auto Maxima are idiot proof... it will not downshift if the speed is too high for the selected gear.
